Improved iaijutsu focus

Specifics: The extra damage you inflict when you make an Iaijutsu focus check no longer has a maximum die cap. The progression of extra damage continues indefinitely, increasing by +1d6 for every 5 points over a result of 10 you receive on the check. For example, an Iaijutsu Focus check of 76 would inflict +14d6 points of damage.
